Hello!

My name is Oleksii, I am the CEO of Mobiwolf, a company that has been specializing in mobile development for Android and iOS for over 14 years. We have extensive experience working with Bluetooth/BLE, including medical sensors, background services, and precise push/audio notifications.

💡 What we can offer for your project:
• App development with connection to Coospo HW706 via BLE;
• Operation in the background while adhering to Android restrictions (Doze Mode, Background Execution Limits, etc.);
• Implementation of notification logic when the pulse exceeds limits;
• Clean organization of the GIT repository and delivery of the ready APK;
… • Work exactly according to the attached requirements and design.

Possible technology: Kotlin (the most reliable choice for background BLE on Android), but we will also consider Flutter — if there is a need for further cross-platform compatibility.

📦 We are also ready to receive the sensor by mail, as specified — we have a legal entity (FOP) and experience working with clients under such conditions.

If you are interested — we will gladly discuss the details, provide estimates for cost and timelines, and develop a clear implementation plan.

Best regards,
Oleksii Karaykosa
CEO at Mobiwolf

Good day!

I have thoroughly familiarized myself with your pulse monitoring app project and am interested in its implementation. I have 7 years of experience in Android app development with a focus on high-performance solutions.

Your project particularly caught my attention due to the need to work with Bluetooth, background processes, and audio notifications - these are exactly the areas where I have practical experience. In particular:

Bluetooth integration: I have worked with various Bluetooth devices, including BLE, implementing stable connections and real-time data processing.

Background processes: I have experience working with Foreground Services, WorkManager, and other mechanisms to ensure stable app operation in the background even when the screen is off.
…
Notifications and audio: I have implemented notification systems with priority settings, high-volume sound triggers, and modal windows.

For your project, I propose using Kotlin with the MVVM architecture and Android Jetpack components to ensure stable and reliable operation. This will allow for the creation of an optimized app that will work reliably on various devices.

I am ready to start working immediately after receiving the sensor and clarifying the details.

Good day, I can implement this project in Flutter. I have experience with Bluetooth devices (mfd057) and background work. I have also worked with an application in the healthcare field.

Here is my portfolio: https://maksklm.carrd.co/

The requirements are clear, but some points need to be discussed (for example, notifications in modal windows).

Hello ✌️

I have experience in developing Android applications, particularly with Bluetooth integration for sensors, and I understand how to implement functionality for background tasks. I have used both React Native and Flutter for similar solutions, so we can discuss the choice of technology in more detail.

The project is interesting, and an important part is the correct processing of the pulse and notifications in the background. I will implement this according to all requirements and test it.

Message me privately, and we will schedule a meeting to discuss everything.
